The aquatic-terrestrial transition areas, riparian zones, recognized as biodiversity hotspots, are increasingly subjected to various stressors, including chemical contaminants such as pesticides. These compounds can be transported into the riparian zone, from surrounding agricultural fields, e.g., via surface runoff, but also from the aquatic environments, e.g. during flooding events. However, little is known about how flood f...

Water scarcity can intensify streamflow reduction, alter hydromorphology, increase chemical pollution, and disrupt resource exchange between aquatic and terrestrial ecosystems. However, the effects of streamflow reduction on pesticide concentrations in sediment, and how these changes influence aquatic insect emergence and riparian spider communities, remain poorly understood. We conducted a 39-day mesocosm experiment in Southw...
